Fluid–structure interaction approach with smoothed particle hydrodynamics and particle–spring systems

This paper presents a novel three-dimensional fluid–structure interaction (FSI) approach, where the meshless smoothed particle hydrodynamics (SPH) method is used to simulate motion of incompressible fluid flows, whilst structures are represented by simplified approach based on particle–spring systems. The proposed FSI technique allows use independent spatial–temporal resolutions for and structural computational domains. elastic constants calibrated relationships with mechanical material properties, Young’s modulus Poisson’s ratio, determined. Fluid structure domains separated interfaces made triangular elements whose position updated during simulation following deformation. coupling two media at handled introduction solid boundary particles. automatically without introducing further complexity, avoids penetration particles into domain. efficiency accuracy present validated analytical/benchmark solutions from literature.
